| No format is inherently better than the other; it just depends on how you want to launch your software. If you'd prefer your application on HOME Menu, '''CIA''' format is the way to go.

| There is also '''NDS''' <code>.nds</code> format software, which can only be used with [https://wiki.ds-homebrew.com/twilightmenu/installing-3ds TWiLightMenu++]/nds-bootstrap and can be launched by placing the <code>.nds</code> file anywhere on the SD card visible to TWiLightMenu++. This format of homebrew is also compatible with the DSi and with DS flashcarts. Alternatively, you can create a forwarder that points to the <code>.nds</code> file on your SD card, which will show up on your HOME Menu.
